OF QUINCY, ILLINOIS, A CORPORATION OF ILLINOIS OIL CONTROL This invention relates to an improvement in oil controls.

The object of the invention is to provide an oil control for oil burners which may be is placed in the center of the latter so as to effectively control the flow of oil to the burner and to maintain approximately the same oil level therein, regardless of any deviation or variation in the position of the burner support.

Oil burners of this character are devised particularly for heating chicken brooders and it very often happens that the floor of a brooder will sag considerably between the burner and oil tank or source of supply,

causing a variation in the oil level maintained in the burner often to such an extent as to overflow the burner bowl and create a fire in the brooder itself, which often destroys the latter and causes considerable other damage.

This sagging of the floor also has a tendency to tilt the burner to one side to such an extent that the oil very often overflows one side of the burner while being drained from the other. Heretofore, it has been customary to mount an oil control at a point remote from the burner to such an extent that it could not very effectively take care of these deviations in the position of the oil burner, and it could not effectively prevent an overflowing of the oil, but this is accomplished by the oil control embodied in this invention.

Whenever the oil control or float cham ber therefor is mounted on the outside of the burner bowl, it would not maintain the proper oil level in the burner, regardless of the tilting of the burner in any direction.

This invention provides for locating the float chamber approximately at the center of the burner bowl, in which position it maintains the proper oil level in the bowl approximately at all times, regardless of any substantial deviation in t he direction in which the oil burner may be tilted. The same oil level is maintained within the float chamber, as in the burner bowl, and since the former is carried by the same support which carries the burner bowl, the two will Application filed October 27, 1927.

be tilted together, and if the burner is tilted in any direction, the rise in the oil level in the burner will also raise the level in the float chamber, which will thereby tend to cut oil the flow of oil sufficiently to lower the oil level in the burner and preventing an overflowing of the burner bowl, likewise preventing any destruction or fire within the brooder.

Suitable valve mechanism and associate construction is connected with the float chamber and float for regulating the flow of oil to the burner bowl and this also provides not only the float control for the oil but also a manual control for regulating the oil level in both the burner and float chamber.

In the accompanying drawings Fig. 1- is a perspective view of the com plete burner;

Fig. 2 is a vertical sectional view therethrough; and

Fig. 3 is a detail plan view of a portion of the burner bowl and float chamber.

The numeral 1 designates the support for the entire burner and float chamber, upon which is mounted an elbow 2 connected by means of a suitable pipe 3 with a source of oil supply or tank (not shown). Extending upwardly from the elbow 2 is a nipple t, in the upper end of which a valve seat 5 is formed for a purpose hereinafter dw scribed. A T 6 is mounted on the nipple 4-, oneend of which carries a coupling 7 which. in turn, supports a casting S in which the lower end of the float chamber 9 is secured, an opening being provided through the bottom of the float chamber 9, the casting 8 and coupling 7 into the T 6, as clearly shown in Fig. 2. A cover sleeve 10 fits over the float chamber 9 so as to cover the latter. Mounted within the float chamber 9 is a float 11 of suitable construction mounted on a valve stem 12, having its upward movement regulated by the nut 13, screwed onto the valve stem. The valve stem extends through the bottom of the float chamber 9, the casting 8, coupling 7, T 6 and nipple 4, and is provided with a needle valve 1 1 formed on the lower end thereof in position to engage the valve seat 5 in the upper end of the nipple 4c for regulating the flow of oil from the pipe 3 and elbow 2 into the T 6. r r V The casting 8 has arms extending lat erally therefrom, as shown in Fig. 1, upon the outer ends of which the burner bowl 16 is supported by means of the small tubes 17 which communicate with the burner bowl and arms 15. The casting 8 has an oil chamber 18 therein, as shown in- Fig. 2, which communicates through the arms 15 and tubes 17 with the channel of the burner as to deliver oil to the burner bowl.

A union- 19 screws into the side of the T 6 and is provided with a valve seat 20 in the inner end thereof for receivingthe needle valve 21, which is regulated by the shaft 22 extending to a hand wheel 23-, shown in Fig.

7 1, and it also carries a pointer 24 for indicating the extent of movement of the shaft and valve 21,

Sleeved over the union 19 and butting against the outer end ofthe T 6 is a hollow' bushing 25 communicating with the interi or of the union 19 and T6 through the lateral openings 26. This hollow bushing 25 also communicates at its upper side with the chamber 18 in the casting 8 through tube 27, also shown in Fig. 2. The burner bowl 16 may be provided with screens 28 and 29.

In the operation of the burner, the oil passes from the tube 3 which leads to any suitable source of oil supply intorthe" elhow 2 and through the nipple" 1 about the valve 14 into the T 6; The oil passes from the T 6 in two directions, up through the coupling 7, casting 8 and into the oil chamber 9 bearing up the float 11 therein, which through the medium of the valve stem 12 and valve 14; regulates the passage of oil through the valve sea-t5 into the T 6. The oil also flows from the T 6 through the valve seat 20 and openings 26 into the hollow bushing 25, from where it passes through the tube 27 into the oil chamber 18, which, in turn, directs it laterally in two directions through the arms 15 and tubes 17 into the burner bowl 16.

. As it is consumed in the burner bowl, the float 11 will gradually maintain the valve 14: slightly open, allowing a continual flow of oil into the float chamber or burner bowl. The passage of the oil to the burner bowl is also regulated by means of the manually controlled valve 21.

As well understood, in burners of this character a constant oil level is maintained in thefloat chamber as well as in the burner b'owl, thisoil level being the sa-mein both. Since the oil in the burner bowl is main tained at the same level as in the float Cllillllf her, it: isdes-irable that these shalliv he as nearly as possible on the same level, but where the float chamber is placed externally of the burner bowl, as is the usual custom, this has been virtually impossible, and it has also been impossible with any degree of accuracy to obtain anything like a constant level of oil in both the float chamber and burner bowl in the event that the latter should tilt in any direction.

It will be apparentth-a-t a tilting of the burner'bowl' also causes a tilting of the float chamber, but if this should be in the opposi'te' direction from the float chamber it will be evident that thesameoil level in the latter will cause an overflowing of the burner bowl, which often. results invery' serious damages and injury, with very often the destruction of the brooder.

By placing the float'chamb'er' in the center or middle of the round burner bowl, this is eliminated to a very-h-iglrdegree and to an extent not heretofore attained. It will be evident that atilting of the burner bowl in any direction will cause a corresponding tilting of the float chamber, and by reason of its location in the center of the burner bowl, there will besubstantially no difference in the relative positions of the two and the oil levels maintained therein. 1
